Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@formmy/store

这是一个为 formmy 设计的状态管理类,它具有以下特性:

  • 在设计上它是和 formmy 解耦的,可以被用在任何合适的场景中
  • 更新状态的方法支持直接设置值,也支持 reducer 的方式更新
  • 值变更的监听器可以是同步或者异步的
  • 支持进行状态重置,恢复到初始状态
  • 接口设计友好,类型完备

Usage

import Store, { updateState } from '@formmy/store';

// 创建 store
const store = new Store({ username: '', password: '' });

// 获取 state
console.log(store.state);

// 监听值变更
store.subscribe({
  // 值选择器,不传时直接选择完整的 state
  selector: (state) => state.username,
  listener: (value) => {
    // 值变更时触发回调,会进行浅比较来避免无谓的更新
  },
  // 是否立即触发,默认为 false,即异步触发
  immediate: true,
  // 是否忽略 reset 引起的值变更,默认为 false
  ignoreReset: true,
});

// 更新值
store.update({ username: 'Lee', password: '123456' });
// reducer 的方式更新值
store.update((prev) => ({
  ...prev,
  username: 'MiseryLee',
}));

// 重置状态到初始值
store.reset();

// 清空监听器
store.clear();

// 帮助函数,使用 reducer 函数来进行对象更新
updateState({ foo: 'bar' }, (prev) => ({
  ...prev,
  foo: 'baz',
}));

//
